PMN use case-1: my gene
• Search for the gene • find reaction
• find other genes annotated to the same reaction • find pathway
• find upstream and downstream genes

Future Development
• Further enhance accuracy of enzyme function predictions
• Annotate transporters and subcellular location of reactions
• Develop genome-scale metabolic models
• Provide online database creation service
• Provide web app for integrated view of metabolism with other information such as gene expression
